Dont worry--The SL guys are damn near coma tose when it comes to technically/mechanically inclined interests-with a few exceptions. I can rarely get an answer to any questions I have about them. The guy who stuck a V12 in the 450sl is a wildman, How I wish the w123 had the same front suspension as the w114-115-r107,it was voted as the best car of the 20th century by road n track around 02-3, that same front end would have made it SOOO much better though !!!!!!!!! Whats a 202??
